Postnuke PHP MySQL Special Characters Problem

[bullwinkle]

I've just upgraded a site from MySQL 4.0.24 running on PHP 4 to MySQL 5.0.19 running on PHP 5.

When I migrate the data in SQL format the UTF-8 special characters don't work. So to get things running, I saved the data locally which removed all the special characters and everything worked. However, when I go back to add in these special characters like £ it corrupts that record and the data after that special character is lost.

I'm running Postnuke and I've looked through the code and I don't see anything that would prevent this from working - it used to work.

Can anyone help me debug this problem - I'm just not familiar enough with character encoding.

Thanks.
